Abstract
In a method for multicasting in a radio network, having at least one base station and multiple mobile terminals, the broadcast message is broadcast from the base station, and the broadcast message is received at the mobile terminals. Furthermore, a broadcast message is formulated as a multicast message, and a token is delivered to a selected group of mobile terminals. The token is needed to recover the information of the multicast message. The selected group of mobile terminals includes at least two mobile terminals. The token is used by the selected group of mobile terminals to allow the reception and recovery of the multicast message.
Claims15
A method for multicast in a mobile telecommunications network, which includes at least one base station and a plurality of mobile terminals, comprising:
- broadcasting the message from at least one base station,
- receiving the broadcast message at mobile terminals,
- formulating at least one broadcast message as a multicast message,
- delivering a token needed to recover the information of the multicast message to a selected first group of mobile terminals using point-to-point short messaging, the selected first group of mobile terminals including at least two mobile terminals, and
- using the delivered token at the selected first group of mobile terminals to allow the reception and recovery of the multicast message.
An arrangement for multicast in a mobile telecommunications network, comprising:
- a message source for generating broadcast messages,
- a broadcasting entity for controlling the broadcasting of the broadcast messages,
- base stations which broadcast the broadcast messages,
- mobile terminals which receive the broadcast messages,
- a delivery unit for delivering a token to selected mobile terminals via point-to-point short messages, and
- an enabling unit for enabling multicast message reception and recovery of broadcast messages at the selected mobile terminals using the token.
